Microbiotests are a useful tool in acute toxicity investigations for the pre-screening and screening of chemicals and wastes. However, some of the enzymatic activity of the test organisms may be used as a signal for chronic toxicity.The composition of a battery of microbiotests depends on the question being asked, and on the answer being tested. In general, a battery of microbioassays should contain representatives of the producers (algae, higher plants), consumers (mostly zooplankton or zooedaphon invertebrates), and decomposers (bacteria or fungi). The selection of particular organisms, and design of the bioassay, depends on the origin and characteristics of the sample. Soil or sediment samples, partially-coloured or turbid samples of surface and wastewater, or totally transparent samples from deep-well monitoring systems, all require different approaches. Microbiotests for the detection of specific toxicants, such as pre-screening for microphyte toxins (see our other paper in same proceedings), is an another example of a situation where sensitive selection of the testing procedure is necessary, bearing in mind the time and cost benefits, as well as ecological reliability. We conclude that well-experienced ecotoxicologists can select the right test organisms and design from a broad spectrum of microbiotests, in order to be able to give a correct interpretation of the ecotoxicological results.
